Progress in clinical oncolytic virus-based therapy for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) carries a dismal prognosis, with advanced disease being resistant to both radiotherapy and conventional cytotoxic drugs, whilst anti-angiogenic drugs are marginally efficacious. Oncolytic viruses (OVs) offer the promise of selective cancer therapy through direct and immune-mediated mechanisms. The premise of OVs lies in their preferential genomic replication, protein expression and productive infection of malignant cells.

FGFR3 and Ras gene mutations are mutually exclusive genetic events in urothelial cell carcinoma.

Fibroblast growth factor receptor 3 (FGFR3) mutations are frequent in superficial urothelial cell carcinoma (UCC). Ras gene mutations are also found in UCC. As oncogenic activation of both FGFR3 and Ras is predicted to result in stimulation of the mitogen-activated protein kinase (MAPK) pathway, we hypothesized that these might be mutually exclusive events.

Interpretation of medication pictograms by adults in the UK.

Background: Patients' ability to understand information about medication is crucial for safety and effectiveness. Rates of illiteracy worldwide indicate that written information alone cannot meet many patients' needs. Medication pictograms are an alternative, but may be culturally sensitive.
